Description

Machining tool
Technical Field
The utility model belongs to the mechanical structure field, concretely relates to machining cutter.
Background
In the process of machining a workpiece, in order to meet technical requirements, holes need to be drilled on a formed metal workpiece, and because the force required for drilling and cutting the holes on the metal workpiece is large, a machine is often adopted to drive a cutter to machine the holes. Some workpieces need to be provided with annular grooves at the periphery of holes after being perforated by the workpieces under specific requirements, in the prior art, the workpieces are perforated by a hole cutter firstly, then the groove cutter is replaced to open the grooves at the outer sides of the holes, the machining rhythm is slowed down due to frequent replacement of the cutter, errors are accumulated due to repeated positioning of the cutter, and errors occur in the relative positions of the holes and the grooves.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem to the current situation of prior art, and provide a machining cutter.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: a machining tool is proposed, comprising: the cutter handle is used for being connected with a lathe;
the tail end of the first blade is connected with the end part of the tool handle, and two opposite grooving blades are arranged on the periphery of the front end of the first blade;
the tail end of the second blade is connected with the first blade, the front end of the second blade is provided with a perforating blade, and a slotting gap is formed between each slotting blade and the tail end of the second blade.
In the above machining tool, a chamfer edge and a butting face are arranged at the joint of the first cutting edge and the second cutting edge, and the butting face is connected with the chamfer edge.
In the above-mentioned machining tool, a chip groove has been seted up on the second cutting edge, chip groove one end extends to on the first cutting edge.
In the above-mentioned machining tool, the shank, the first blade and the second blade are integrally formed.
Compared with the prior art, the utility model has the advantages of this machining cutter can be to work piece trompil and annular, guarantees that the interval between hole and the annular accords with the requirement of machining precision, avoids the condition that the processing rhythm becomes slow that causes many times of wonderful cutter.
Drawings
FIG. 1 is a detailed structural view of the present machining tool;
in the figure, a shank, a first blade 2, a grooving blade 3, a second blade 4, a grooving blade 5, a grooving gap 6, a chamfering blade 7, an abutting surface 8 and a chip groove 9.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, the present machining tool includes: the cutter handle is used for being connected with a lathe; the tail end of the first blade 2 is connected with the end part of the tool handle, and two opposite slotting blades 3 are arranged at the periphery of the front end of the first blade 2; the tail end of the second blade 4 is connected with the first blade 2, the front end of the second blade 4 is provided with a perforating blade 5, and a slotting gap 6 is arranged between each slotting blade 3 and the tail end of the second blade 4.
The cutter handle is connected with a lathe, so that the lathe drives the cutter handle to rotate, because the tail end of the first cutting edge 2 is arranged at the end part of the cutter handle, and the tail end of the second cutting edge 4 is arranged at the front end of the first cutting edge 2, when the lathe drives the cutter handle to move forwards, the second cutting edge 4 firstly contacts with a workpiece, along with the rotation of the cutter handle, the perforating edge 5 on the second cutting edge 4 can perforate the workpiece, along with the advancing of the cutter handle, the perforating depth of the second cutting edge 4 on the workpiece is deeper and deeper, and the first cutting edge 2 can gradually approach the workpiece until the perforating edge 3 at the end part of the first cutting edge 2 abuts against the workpiece, and further along with the rotation of the cutter handle, the perforating edge 3 can perforate a ring groove on the workpiece, because the perforating gap 6 is arranged between each perforating edge 3 and the tail end of the second cutting edge 4, the position of the ring groove is not in contact with, the processing mode avoids repeatedly positioning the cutter, ensures the distance between the hole and the ring groove, and improves the processing precision.
The joint of the first cutting edge 2 and the second cutting edge 4 is provided with a chamfer cutting edge 7 and an abutting surface 8, and the abutting surface 8 is connected with the chamfer cutting edge 7.
When the workpiece is provided with the annular groove, the chamfer edge 7 can be used for chamfering the end part of the hole, and the abutting surface 8 can abut against the workpiece along with the advance of the tool handle, so that the tool handle cannot continue to be pushed forwards, the first tool edge 2 and the second tool edge 4 cannot continue to be pushed forwards, and the depth of the annular groove and the depth of the hole are controlled.
A chip groove 9 is arranged on the second blade 4, and one end of the chip groove 9 extends to the first blade 2.
When the first blade 2 is used for processing a hole, scraps in the hole can be discharged to the tail end of the chip groove 9 through the front end of the chip groove 9, and when the second blade 4 is used for processing a hole, scraps in the groove can be discharged through the tail end of the chip groove 9.
The knife handle, the first knife edge 2 and the second knife edge are integrally formed.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
